This is the balanced equation.


We have given that,


1.295g of Aluminum reacts with 0.48g of Oxygen


 No. of moles of Al = = 0.048


No. of moles of oxygen= = 0.031


For 4 moles of Al we need 3 moles of


0.048 moles of Al we need 0.03 moles of

Therefore some oxygen is left behind


Hence, Aluminum is limiting reagent.
